These two years on the lard controversy is quite a lot, some people say that lard is very healthy, some people say that want to be healthy to eat less lard it, then lard in the end healthy or not?

A, what is lard

Lard, also known as meat oil or lard, is one of the edible oil from the pig's fatty tissues extracted by heating.

The main component of lard is fat, and its fatty acid composition is relatively balanced, with saturated fatty acids (SFA) accounting for about 43.2%, monounsaturated fatty acids (MUFA) for about 47.9%, and polyunsaturated fatty acids (PUFA) for about 8.9%.

In addition to fat, but also contains vitamin A, thiamin and other essential vitamins and trace minerals, lard in trace amounts of special proteins and some of the glycerol ester decomposition products volatilized can produce a unique flavor, enhance the human appetite.

Overall, lard is a nutrient-rich food.

Two, eating lard is actually good for health?

First of all, being nutritious is not the same as being the healthiest, because lard is too high in saturated fatty acids! The dietary guidelines of various countries recommend reducing the intake of saturated fatty acids. But lard is up to 40% saturated fatty acids, which is nearly three times as much as regular vegetable oil!

Saturated fatty acid intake will significantly affect blood lipid levels, increase the risk of cardiovascular disease and death, and unsaturated fatty acids, polyunsaturated fatty acids, can reduce the body's "bad cholesterol" and triglyceride levels, the health benefits. The fact that they are not in the same place as the other fatty acids is a good sign that they are not in the same place.

Simply from the proportion of unsaturated fatty acids, lard in animal oil esters in the performance of excellent, unsaturated fatty acid content between butter and olive oil, which is part of the people advocating the eating of lard, however, intake of lard there are close to the same amount of saturated fatty acids into the human body.

High saturated fatty acid diet for endogenous cholesterol synthesis provides a lot of raw materials, so that cholesterol levels rise, and even cause hypercholesterolemia, hoarding in the blood of excessive cholesterol is not a vascular killer easy to cause coronary heart disease, stroke and other atherosclerotic diseases.

So, it seems that lard, although rich and delicious? Or eat less healthier!

Three, lard than vegetable oil which is more healthy?

Most families choose to cook with vegetable oil and feel that eating vegetable oil is healthier than lard, but in fact, this view is not comprehensive.

The composition of vegetable oil is mainly polyunsaturated fatty acids and monounsaturated fatty acids, too much saturated fatty acids can easily lead to cholesterol and blood lipid elevation, while polyunsaturated fatty acids have the effect of lowering blood lipids and protecting blood vessels, but does not mean that the more polyunsaturated fatty acids the better.

Because unsaturated fatty acids contain more unsaturated bonds, it is easy to oxidize in the body and produce excessive peroxide, which will promote the aging of the body, cell death and tumor formation.

So, long-term only eat vegetable oil is not the healthiest choice, saturated fatty acids, polyunsaturated fatty acids, monounsaturated fatty acids, the composition of these three fatty acids on the human body have different roles to follow the health requirements of the selection of a reasonable nutritional mix. In accordance with the recommendations of the Chinese Nutrition Society, the optimal ratio of these three fatty acids is 1:1: 1.

Four, we should eat what oil?

The correct way to eat oil should be small and balanced. Each time the oil control in about 10 grams, and lard, vegetable oil should be eaten, after all, saturated fatty acids are also essential.

Saturated fatty acids provide energy for the body, and can be converted to fat to help maintain body temperature after ingestion, and also promote the production of cholesterol, which is an important component of cell membranes that can maintain cell structure.

No matter what kind of fatty acid, as long as the intake is reasonably controlled, there are some benefits to the human body, while excessive intake will have adverse effects on the body.

My family will eat a little bit of any oil, in my opinion, the nutritional advantages of each oil is different, it is best to use alternately, to avoid long-term single use of a certain kind of fat and nutritional imbalance caused by the hidden danger.
